SLR 4 - Need for operating Systems

What is the primary role of an operating system?

• To control the computer's hardware and software resources

• To create complex computer programs

• To write applications for specific hardware

• To design computer hardware

Why were early computer programs complex and difficult to create?

• They had to include all the code to run the computer

• They were written in multiple languages

• They required advanced hardware

• They had to be compatible with all operating systems

Which of the following is NOT a basic function of an operating system?

• Memory management

• Processor management

• Security

• Application development

What does the operating system act as for other software?

• A platform on which the other software can run

• A hardware component

• A network interface

• A programming language

How is the functionality of a computer typically split?

• Hardware, Operating System, Application, User

• User, Application, Operating System, Hardware

• Application, User, Hardware, Operating System

• Operating System, Hardware, User, Application

What does processor scheduling in an operating system determine?

• The type of user interface

• The security level of each process

• The amount of memory each process will use

• The order in which processes will be executed

What is the role of memory management in an operating system?

• Providing a user interface

• Recording how memory is divided and identified

• Handling input/output devices

• Managing user permissions

What does secondary storage management involve?

• Tracking where files and programs are stored

• Providing a user interface

• Managing the processor's work

• Allocating memory efficiently

How does the operating system support security?

• By scheduling processes

• By ensuring resources are protected from unauthorized access

• By providing a user interface

• By managing input/output devices

What does the operating system hide from users and other software processes?

• The security protocols

• The application layer

• The user interface

• The complexities of the hardware
